OMK Belgorod Plant Supplies Stamped Blanks for Akkuyu NPP
In 2020, United Metallurgical Company OMK’s Belgorod power engineering plant (Belenergomash-BZEM Ltd.), a Metal-Expo regular exhibitor, produced 60 tonnes of stamped body forgings for the manufacture of valves supplied to the first and second power units of the Akkuyu nuclear power plant under construction in Turkey. The customer of the company's products is one of the leading suppliers of pipeline valves for nuclear power plants Energopotok in Nizhny Novgorod region. One-piece forged valve bodies made of austenitic (corrosion-resistant chromium-nickel) steel are recently mastered by the plant, new for the industry products for nuclear power plants. They have increased corrosion resistance and can be used in aggressive environments. The shape of the supplied blanks practically repeats the shape of the finished products, therefore they require minimal machining. This allows customers to save time and consume less metal than when using standard forged blanks, which require long-term machining to the required geometric dimensions.
In 2021, the OMK Belgorod plant will supply another 60 tonnes of stamped forgings of austenitic stainless steel bodies for the manufacture of valves of the third and fourth power units.
As a sub-supplier in 2019, OMK Belgorod Plant has already supplied its products for the construction of the first and second power units of the Akkuyu NPP. In particular, the plant manufactured 50 tons of bellows expansion joints with a diameter of 200 to 1400 mm, 44 tons of forgings made of carbon and low-alloy heat-resistant steel for the manufacture of sealed pipeline penetrations in the contour wall of power units No. carbon steel for the manufacture of fastening elements for the tank of the emergency cooling system of the zone of the first two power units of the nuclear power plant.
After completion of construction, the Akkuyu NPP will become the first nuclear power plant in Turkey. The project includes four power units with VVER-1200 generation 3+ reactors of Russian design. Commissioning of the nuclear power plant is scheduled for 2023, by the centenary of the founding of the Republic of Turkey.
